Plastics Mold Classification 101-105 There are five PLASTICS mold classifications. Class 101 has the highest quality, cycles, and production levels; Class 105 has the lowest quality, cycles, and production levels. In order to account for the wear and tear that occurs as a result of mechanical processes, these estimates are based on injection molding shots (the number of times the mold is filled and opened), rather than on the number of parts injection molding are produced.

All in all, tooling does not reach its maximum capacity after 1 million shots. Some of the tools here at Junying are capable of firing over a million shots per year; some have been known to fire over 20 million shots before needing to be replaced.

When any of the following issues are identified, you should begin to consider replacing your tooling:

When a piece of tooling reaches the end of its useful life, program costs typically begin to rise. Watch out for costs associated with scrap rates, tool repairs, labor for sorting or other operations, and the chaos{anchor} results from issues such as orchestrating returns, line downs, and vendor management, in addition to monetary costs.

Your injection molder or toolmaker will be able to identify potentially hazardous conditions with your tooling, and you should be aware of these conditions throughout the operation. At-risk conditions are typically maintained through repairs, but most repairs can only be performed so many times before the tooling needs to be replaced. When repairs are no longer holding up or parts are becoming worn down, it is time to consider replacing your tooling.
